Coarse open pore foam
Fine open pore inner foam
Adhesive withstands repeated cleaning
Smaller than stock size
Increased air space and circulation
Coarse open-pore foam catches airborne dirt, grime, and sand. Fine open-pore inner foam acts as a second filter to trap the smallest particles while ensuring maximum air passage. Adhesive withstands repeated cleaning. Smaller than stock to increase air space and circulation around the filter.
